The whole concept has merit, if it happens or not time will tell.
For starters, ESPN is paying the all three conference, the SEC, ACC and Big 12 to carry their game. Disney is having issues with linear TV, but sports is one of the few profitable areas left. Question is do they sell off their rights to the ACC and Big 12 and go all in in the SEC? Who knows, but Disney is probably willing to listen to something, and they could push the deal to get FSU, Miami, NC and Clemson into the SEC or Big, so now they have formed their "super league" they package that bundle, and if they can sell off their deals with the ACC and Big 12, they probably would. Cable cutters are causing, and costing Linear TV a lot of problems, look at the regional sports networks, Root sports selling to the Mariners is just a tip of the iceberg, the regional sports networks have been decimated by "cord cutters", many regional sports networks have gone out of business in the past couple of years, there and MLB teams with no regional sports network right now, the Mariners problems with Root is not unusual, it is happening everywhere in baseball, hockey and basketball.
We are entering a new era in sports, realignment in College sports are just part of the change, how we watch these sports and who pays the teams and how and who the viewers pay is also changing.
The Pac 12 is not getting back together with the most recent 12 teams, but 4-6 of them could come back, and forming a 3 or 4 division league between the ACC, Big 12 and Pac 2 , might be the only way to keep pace with the super league. Look at the teams willing to pay 1 million or more for a transfer QB, if you are not one of them, you may not be in the Big or SEC much longer. However being in a conference that is a close 2nd that stretches coast to coast that does not have an unlimited pool of NIL money, will possibly build a stronger viewer ship. So, there is probably some company willing to pay for it and package it up and sell it.
Does this guy have inside knowledge? Who knows, but one can logically come up with an argument as to why this would happen. Doesn't mean it will, because you have university Presidents and egos involved, and we saw how that worked for the Pac 12.
